ABSTRACT A water isolation system comprises a valve (1) in a water flow line (10), with a latched solenoid to open or close the valve. A power source operates the valve with an electrical switch (2) causing pulsed actuation of the solenoid on operation of the switch. The solenoid is unpowered when the switch is not being operated. The switch (2) is located at a convenient point within a building to which the water is supplied, which point may be remote from the water flow line, such as adjacent a main entry/exit door to the building. Use of the system allows the water supply to be completely isolated when the building is to be unoccupied for even the shortest period of time. It also prevents excessive water loss and water damage when there is a burst pipe by being controlled at a point which is easy to reach and thereby switch off the system quickly. Finally, it can be easily closed to facilitate maintenance or replacement of any part of the water or heating system within the building.
